Understand Subscription Backdating

Use Subscription backdating when you need to align billing with an earlier service date, correct a delayed entry, or honor a start date carried over from another system.

What is subscription backdating?

Subscription backdating begins on a date earlier than the day it's created. This lets you accurately reflect a Customer's billing timeline, especially in scenarios such as:

• The Customer had access to the Plan or service before completing a formal signup.
• You're migrating Subscriptions from another system and need to honor historical start dates.

When backdating a Subscription, keep these limits in mind:

• You can only backdate a Subscription by one billing period at most (for example, one month for monthly billing).
• You cannot backdate a Subscription earlier than your configured lock or close date, if one is set.
• Whichever of these two limits is more restrictive determines the earliest date you can select.
• You cannot create a backdated Subscription within a Subscription Group.
• Even if a Subscription is backdated, its first Invoice date is always today's date.

Backdating availability and limits

Subscription backdating is available whenever your site uses invoice-centric billing. There's no separate setting to turn backdating on.

The earliest date you can select is whichever of these two limits is more restrictive:

• Your site's configured lock or close date, set under Advanced Finance Settings using the Dynamically Update Closing Date and Dynamically Update Locking Date options (Manual, a fixed number of days prior to today, or the end of the previous calendar month). See Manage Closing and Transaction Lock Dates for how these dates work.
• One billing period back from today, adjusted for the Plan's trial length and any Product-specific billing intervals.

Best practices

• Review your site's lock and close settings before backdating a Subscription.
• Turn off dunning when retroactively entering a Subscription that shouldn't initiate collections.
• Communicate with your billing or finance team before creating backdated entries to avoid confusion in reporting.
• Use monthly billing if you require Calendar Billing.
• Toggle Evergreen status carefully, if future billing behavior is critical.
• Keep the live preview open for visibility into how your changes affect billing.

Controlling dunning behavior

You can control whether backdated Subscriptions trigger dunning (collections) processes. This determines whether Customers receive notifications about unpaid balances from prior billing periods. See Understanding How Dunning Works for how dunning works in general.

Enable dunning if you want the system to automatically pursue collections and send reminder emails for any past-due amounts.

Disable it if the backdating is used for internal adjustments or data clean-up and you don't intend to collect outstanding payments.

Important: If a backdated Subscription has automatic payment enabled and the initial payment attempt fails, what happens depends on your dunning strategy's Trigger Dunning For Backdated Subscriptions setting. If enabled, the Subscription is still created and immediately enters dunning. If disabled, which is the default, the Subscription is not created at all.

If you want a failed initial payment to still create the Subscription and start dunning, enable Trigger Dunning For Backdated Subscriptions in your dunning strategy. Otherwise, use a manual payment method during creation to avoid a failed-creation outcome.

See Understand Dunning Activity for Backdated Subscriptions for how to read the resulting activity log entries.

Impact on invoicing and reporting

Subscription backdating can affect how your system handles invoices, revenue reporting, and recognition. Consider the following:

• Invoice Generation: Invoices may be issued immediately to reflect the retroactive start.
• Revenue Recognition: Revenue is recognized from the historical start date, which impacts revenue schedules and accounting reports.
• Automated Adjustments: Revenue recognition timelines are recalculated to align with the backdated timeline.
